3.5 Regulating the Needle Thread Tension

3.6 Thread Regulator

Pre-tensioning for Thread Trimming

For the sure functioning of the thread trimming with

opened main tension 4 a small residual tension of the

needle thread is required.

This residual tension is achieved by pre-tensioning 3. At

the same time it influences the length of the cut needle

thread end. (Starting thread for the next seam.)

Short starting thread = tighten the knurled nut 3.

As base position applies:

Front of the knurled nut and bolt flush.

Greater adjustments of the pre-tensioning makes a

readjustment of the main tension necessary.

Main tension

Pre-tensioning 3 and main tension 4 should give the

recommended needle thread tension of e.g. 80g.

Set the main tension 4 accordingly.

With the thread regulator 6 the needle thread quantity

required for stitch building can be regulated. The setting

is dependent on stitch length, material thickness and

thread characteristics.

Note:

Only a precisely set thread regulator assures an optimal

sewing result.

The needle thread loop should glide over the hook

without excess and with little tension.

Loosen screw 9 and set the regulator accordingly.

The vertical wire 7 serves as a setting aid in conjunction

with the scale 8.
